A nodule may range in size from several mm to several cm, and may be detected visibly, by examination of the neck clinically, or by ultrasound assessment.
Nevertheless, it is increasingly common for patients to have a thyroid nodule detected "incidentally" as part of an investigation for symptoms in the neck region that ultimately lead to a neck ultrasound and the detection of a thyroid nodule.
Nodules may also be classified as Functioning nodules (or Hot Nodules) or as Non-functioning (or cold), based on the results of radionucliide imaging studies (thyroid scans).
